The Bad Zwesten _ Zwesten wastewater treatment plant is located in the town of Bad Zwesten, in the Schwalm-Eder-Kreis district of Hessen, Germany. The facility serves a population of approximately 5,217, classifying it as a small agglomeration under EU regulations. The plant is situated in a rural, inland area near the Keilmühle district. As a German wastewater treatment plant serving fewer than 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment (typically secondary or equivalent) for discharges into freshwater. The plant is expected to meet national standards for biological treatment and nutrient removal where necessary to protect receiving waters. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Eder River, a tributary of the Fulda River, which flows into the Weser River and then to the North Sea. The plant plays a key role in maintaining water quality in the local watershed, supporting aquatic life and downstream ecosystems.
Environmental context
The plant discharges into local streams that feed the Eder River, part of the Weser basin. The Eder River supports diverse aquatic life and is an important corridor for migratory fish. Downstream, the Weser River flows through northern Germany into the North Sea, making nutrient management critical to prevent eutrophication in coastal waters. The surrounding region is characterized by mixed agricultural and forested landscapes, with sensitive groundwater resources.
